Changing the way fuel injectors are tested

The VPUD’s are compatible with fuel injectors and safety valves from hundreds of different engine models and are continuously modified for new models according to the needs of the respective costumers. Our cooperation with acknowledged engine designers has resulted in unique solutions like:

The extended capability of the test rig ensures a much easier way to verify details critical to the actual injector performance and prevents insertion of injectors that previously would have caused excessive fuel consumption, higher emission and engine fouling.

Reduce Maintenance Costs:

When a fuel injector performs less than optimal it can start opening at the wrong time as well as leak fuel before or after injection. This results in unnecessary fuel consumption and engine maintenance. The new test cycle makes it easier for any engine crew member to judge the state of the injectors that will power the vessel for the months to come.

Replace two units with one:

Normal yard/engine supply one small hand tester for gensets and a big VPU for the M/E. The VPUD 1100SV is designed for testing of both engine types.

Note - Using VPUD 1100 MKI and MKII for MAN slide valves can damage the valves. Use the PPMI 1000 in order to test MAN slide valves with the VPUD 1100.

A slide-valve protection system and a step-by-step test procedure to guide the operator is included as you purchase the VPUD 1100. Additionally we offer several optional, subsequent purchases such as valve holders for more than 150 different injector types, oil mist separators and a test fluid, which we highly recommend for optimization of the VPUD’s efficiency.

The ”Universal Valve Holder” is a fuel injector valve holder with five operating positions and adapters for all common Wärtsilä / MAN Diesel / MaK 4-stroke injectors as well as other engine types upon request from workshops worldwide.
